Patent JP-S5847307-A (JP)
Title: Amplifier
Inventor: KOUNO KOUUN
IPC: H03G1/00
Filed: 1981-09-17
Abstract: PURPOSE:To realize the switching of the AC gain without changing the DC level of an output signal, by turning on and off the common emitter currents of plural differential amplifiers having different gains by means of a switching means in order to set the emitter current at a certain level. CONSTITUTION:The 1st differential amplifier is constituted with transistors TRQ3 and Q5 and resistances R6 and R8 connected to an emitter. At the same time, the 2nd differential amplifier consists of the TRs Q4 and Q6 and resistances R7 and R9. The 1st and 2nd differential amplifiers are turned on and off by the switching TRs Q7 and Q8. The emitters of the TRs Q7 and Q8 are connected to the collector of a current source TRQ9. The bases of the TRs Q3 and Q4 are connected to an input terminal 1, and the collectors of the TRs Q5 and Q6 are connected to a load resistance R10 and an output terminal 2. When the burst gate BG pulse applied to a control terminal 3 is higher than the reference voltage VS, the TRQ7 is turned on. Then the TRs Q3 and Q5 work to obtain a gain R10/(R6+R8). When the BG pulse is lower than the voltage VS, the TRQ8 is turned on. Then the TRs Q4 and Q6 work to obtain a gain R10/(R7+R9). Thus the DC potential is steady with the TRQ9.

Title: Cleaning device for press panel
Inventor: NISHIMOTO YUTAKA
IPC: B08B1/02
Filed: 1992-05-12
Abstract: PURPOSE:To make it possible to monitor correctly the abrasion state of a brush roller during the operation of a cleaning device by comparing the load current value of a motor for the brush stored in a load current value storage means to a set reference value. CONSTITUTION:If a brush roller 74 becomes abraded, a force which presses a work 1 decreases, because the distance between the rotational center of the brush roller 74 and the surface of the work 1 is constant. Consequently, the load brought to bear upon the rotary shaft of a motor MB for the brush which rotates the brush roller 74 decreases, and thereby the load current value of the motor MB becomes low. Therefore, the load current value of the motor MB for the brush is compared with the load current value of the motor MB for the brush is a state where the brush roller 74 is worn out to a specified abrasion level. Then, if the detection current value is larger than the reference value, it is interpreted that the abrasion of the brush roller 74 is below a specified value. Further, if the specified value is set to an abrasion level within a permissible range, it is possible to determine whether the abrasion value of the brush roller 74 stays within a permissible range based on both detection current value and reference value.

Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To enable efficient data transfer by transmitting only partial data, which has not been acquired among prescribed information by an information provider, to an information processor according to the acquisition request of prescribed information. SOLUTION: When data are interrupted in the middle of transmission of data (a)-(c) in the case of data transmission based on the data acquisition request and portable information terminal equipment 10 can not properly acquire the following data (b) and (c), a code, with which data following the data (a) acquired up to the moment can be specified to be received, is added to the data acquisition request when the acquisition of data is requested again. When that data acquisition request is received, a server 15 transmits only the required data corresponding to that code to the portable information terminal equipment 10.  Thus, the portable information terminal 10, which acquires the data (b) and (c), for example, can acquire all the data of required information by adding the already received data (a) with the data (b) and (c) which are received after the data acquisition is requested again.

Title: Manipulated variable generating device and method therefor
Inventor: SAITO YUKIHIRO
IPC: G06F9/44
Filed: 1995-06-14
Abstract: PURPOSE: To provide a manipulated variable generating device/method which can easily generate the proper manipulated variables in response to its upper and lower limit levels and also can easily cope with the changes of both limit levels. CONSTITUTION: The upper and lower limit levels, i.e., the targets of the state quantity of a controlled system are inputted to an input means 12, and a state quantity detection means 13 detects the state quantity of the controlled system. A deviation calculation means 14 calculates an upper limit level deviation between the state quantity and its upper limit level and also a lower limit level deviation between the state quantity and its lower limit level respectively. Based on these calculated deviations, a manipulated variable generation means 15 generates a manipulated variable to control the state quantity of the controlled system. Thus both upper and lower limit level deviations are calculated for the state quantity of the controlled system, and a proper manipulated variable calculated based on both deviations.  Then the proper manipulated variables are easily obtained in response to both upper and lower limit levels of the state quantity. Furthermore, it is possible to easily cope with the changes of both upper and lower limit levels of the state quantity because the manipulated variable is decided based on every limit level deviation not on the upper and lower limit levels and the absolute value of the state quantity.

Title: Nuclear fuel pellet forming device
Inventor: IWANO YOSHIHIKO
IPC: G21C21/02
Filed: 1991-06-19
Abstract: PURPOSE:To prevent cracking on the product and improve the production yield by rotating a disk around a center axis, moving each through hole in turn to the position prepared in advance and forming with top and bottom punches and pushing out with push rods. CONSTITUTION:A formed body guide 2 is firstly pushed up above a dice 1 by a bottom punch 4. Here, nuclear fuel powder 5 is put from the top and it is fabricated by a top punch 6 to form pellets. Then, punches 6 and 4 is drawn out, the dice 1 is rotated and a top push rod 7 pushes the formed body guide 2 to move it to the lower part of the dice 1. In this process, the diameter of the guide 2 increases by ca. 0.4mm and generates a gap to the formed body 8 and so the formed body 8 separates from the guide 2. At this moment, a guide rod 9 supports the formed body 8 to prevent its fall and moves in synchronizm with the top push rod 7. So, the formed body can be lowered to a take-out floor 10 without giving a shock to the formed body 8. By this, the formed body 8 of the powder 5 can be taken out of the press machine without friction with the dice 1.

Filed: 1980-10-21
Abstract: PURPOSE:To improve picture qualities of electric discharge recordings made by a high speed recording, by performing recording on the electric discharge recording paper with a recording pen on which a voltage and a heat are impressed. CONSTITUTION:When a negative voltage is impressed on a pipe 7 of a pen recording section through a lead wire 8, a recording electric current is supplied from a return circuit electrode 11 to the recording layer section of an electric discharge recording paper 1 located between the pipe 7 and an edge 10 through the conductor layer of the recording layer, and then, the recording layer is broken by the electric discharge and the conducting layer is exposed. Thus, the recordings of analog waveforms are performed. At this time, blanked spots and unevennesses in the recording density which may possibly be caused by the electric discharge recording are eliminated or reduced by the stable heating breakage of the recording layer by a built-in heater to which the electricity is supplied through another lead wire.
